2250 Comped Tournament Skaven List

Hello all, here is a list I am thinking about using at comped tournaments, expecting (hope, lol) to comp 8-10, afraid I might comp lower and be @%$#@!.

Warlord, Fellblade, Shield 193
Priest, Flail, 2 scrolls, Furnace 304
Priest, Flail, 2 scrolls 154

4x 21 slaves 168
2 Rat Swarms 50
5 Giant Rats, Pack Master 23
2x 25 Clanrats, Musician, Standard, Shields, Doomflayer 359
24 Clanrats, Musician, Standard, Warpfire thrower, Shields 190

8 PCB's 128
30 Monks, Champion, Standard, Stormbanner 280

Abomination (goodbye high comp...), Spikes 250
Doomwheel 150
2249

I might turn the abomination into a doomwheel but I am unsure, I don't know where I would put those points.
a) what do you think of the list?
b) how do you think it will comp?
c) practice game, anyone?
